This market resolves to YES if evidence emerges that points to the alleged UnitedHealthCare CEO assassin, Luigi Mangione, being the operator of the https://x.com/mister_shroom Twitter/X account. This market is about whether the mister_shroom account was operated by Luigi Mangione, and will resolve YES or NO on this regardless as to whether Mr. Mangione is convicted of the assassination.

I have left the criteria to this market purposefully vague because I am not sure what evidence might emerge that could link the two. Some examples of linkage that would cause me to resolve the market include:

• A personal friend or family member of the alleged assassin linking him with the account

• Messages from the mister_shroom account being leaked that demonstrate the operator of that account to share multiple identifying features of Mr. Mangione, including work or school history, location, personal history, or name

• Luigi Mangione himself saying "I am mister shroom" in court
